Overview

PathValidator checks if filesystem paths exist

This class is designed for dependency injection in tests. Production code uses the real filesystem, while tests inject a mock that returns predetermined results.

Examples:

Production usage

validator = PathValidator.new
validator.exists?('~/dev/project')  # => true/false based on real filesystem

Test usage (see spec/support/jump_test_helpers.rb)

validator = TestPathValidator.new(valid_paths: ['~/dev/project'])
validator.exists?('~/dev/project')  # => true
validator.exists?('~/dev/other')    # => false
